I might be tempted to respond in kind!

My first response would be a song by an English parodist and 'Filker' Zander Nyrond (a.k.a. Jonathon Waite) who's "Backward Christian Soldiers" can be found Here
I will merely quote the first verse, although the 'Filk Blanket Permission List' makes it clear that it can be posted here. ("The following folks have given blanket permission to post their songs, so long as proper credit and copyright information are kept with the song, and it is not published or recorded for sale without specific permission from the writer. ")

BACKWARD CHRISTIAN SOLDIERS
Zander Nyrond
(Tune: fairly obvious really, no?)

Backward, Christian soldiers,
Backward from my door.
Take your sales pitch elsewhere,
Trouble me no more.
Christ and Hare Krishna,
Also Joseph Smith--
These are merely archetypes
From the realm of myth.
CHORUS        
Backward, Christian soldiers,
Backward from my door.
Take your sales pitch elsewhere,
Trouble me no more.
